A system of two linear equations is shown below 2.0 + 3y = 6
-2 + 4y = 8
Henrietta claims that replacing the equation 2x + 3y = 6 with a different equation sometimes produces a
system with the same solutions. Select three equations that can be used to support Henrietta's claim.
A
2 + y = 14
B
2x - 8y = -16
С
4x - 5y = -10
D
-2 + 15y = 30
